Talk:Pourbaix diagram

This article is very misleading. Pourbaix Diagrams show areas of ion predominance (among other things). I will pull out my old lecture notes and return to expand this when i have time.... 220.253.73.96 14:02, 29 March 2006 (UTC)[reply]

Has this ("very misleading", "needs attention from an expert") now been dealt with? - I'm no chemist, but to me the article seems sound & credible (and gives reasonable prominence to the notion of prominent ion). At the time of the Mrch_'06 comment (above) it was under 1000 bytes: within 18 months it was barely recognisable - it's nearly 10 000 bytes now, via over 100 edits. (By Mrch_'09 - "needs attention" - it was 3500 or so.) 95.149.131.76 (talk) 23:50, 8 July 2016 (UTC)[reply]

Not sure how to resolve this, the horizontal pH scale on the iron Pourbaix diagram is incorrect, counting: "0 2 4 6 8 10 11 14".

I just fixed that typo in the figure's X axis. Olawlor (talk) 06:32, 6 April 2019 (UTC)[reply]

Explanation for non-specialist readers

Can this concept be explained to readers who are not electrochemists (and therefore do not know already what it is)?
The head section could use a couple of sentences on the uses of this deiagram, ad the body of the article could include a couple of examples. --Jorge Stolfi (talk) 23:57, 29 March 2019 (UTC)[reply]

Could the vertical axis be something else?

I recall seeing on some journal paper a plot labeled "Pourbaix diagram" for copper compounds where the horizontal axis was pH, as in this article, but the vertical axis was partial pressure of CO₂. The phases included malachite, azurite, copper oxide, cuprate, etc. Does that make sense? --Jorge Stolfi (talk) 00:02, 30 March 2019 (UTC)[reply]

This isn't my field, but there's a paper in Metals discussing more recent generalized Pourbaix diagrams, and they give the example of a 3D voltage-CO2-pH stability diagram.Olawlor (talk) 06:32, 6 April 2019 (UTC)[reply]
